Patent CA-2349145-A1 (CA)
Title: Point of sale (pos) terminal security system
Inventor: HANLEY DAVID C
IPC: G06F21/00
Filed: 2001-05-29
Abstract: A security system for electronic circuits (e. g. electronic circuits contained within a secure POS terminal) is provided that is both more tamper resistant, and tamper responsive and less expensive than the prior art epoxy potting. This is achieved by inserting an electrical connector between a first and a second circuit board contained within a case of the POS terminal. The first and the second circuit boards are any type of circuit board known in the art, including both not limited to, rigid circuit boards, flexible circuit boards, printed circuit boards, etc. If the case is opened the connector no longer provides an electrical connection between the first and the second circuit boards, triggering a tamper detection circuit.      In some embodiments of the invention, a flexible conductive film is wrapped around the circuit boards and the connector. If a tamperer attempts to penetrate the case of the POS terminal to disable the tamper detection circuit, the circuit on the flexible security film is interrupted, in turn triggering the tamper detects ion circuit. As a result, the secure POS terminal of the present invention overcomes the limitations of prior art potted terminals. By eliminating the potting process, in fact, the cost of manufacturing the terminal is reduced and there is no need for a special ventilation system. In addition, the circuitry within the terminal can be accessed for repair and maintenance purposes.

Title: Dome constructing method
Inventor: NIIDUMA YOSHIMI
IPC: E04B1/32
Filed: 1999-11-12
Abstract: A dome constructing method for constructing a spherical dome by assembling a polyhedral skeleton and then by finishing the interior/exterior of the same.      A plurality of joints, which are to be arranged when assembled at the positions of the individual vertexes of a polyhedral skeleton and each of which has a plurality of joint blades in the directions of the individual sides of the polyhedral skeleton, as extended from said individual vertexes, and a plurality of frame members are adopted as members for constructing the polyhedral skeleton of the spherical dome.      Three joints and three frame members are assembled into a triangular frame or a basic unit of the polyhedral skeleton in a grounded state by using the three joints as the vertexes and the three frame members as the individual sides of the triangular frame. Moreover, a new triangular frame is assembled around said grounded triangular frame by using similar frame members and joints, thereby to assemble the polyhedral skeleton of a polyhedral cone such as a pentahedral cone or a hexahedral cone, which uses the joints positioned at one vertex of said grounded triangular frame as its vertex and said grounded triangular frame as its one side.      Each time the polyhedral skeleton of the polyhedral cone is thus assembled, a triangular frame different from said triangular frame is newly grounded by turning said polyhedral skeleton, and the polyhedral skeleton is subsequently assembled by repeating similar assembling works.      Next, said polyhedral skeleton is finished on its interior/exterior to construct the spherical dome.

Title: Bushing arrangement for seal cavity protection in rotating fluid equipment
Inventor: DUNFORD JOSEPH R
IPC: F16J15/34
Filed: 2001-07-24
Abstract: An arrangement of members for a throat bushing for rotary fluid equipment includes a first member that is useful for seal cavities that contain conventional packing, and a second bushing member that will be used in conjunction with the first bushing member if the seal cavity utilizes a mechanical seal at the remote end of the cavity. Both bushing members have a tight sliding fit in the seal cavity and each is provided with spiral grooves in a central bore thereof for the removal of contaminants from the seal cavity. The first bushing member can also be provided with appropriate ports for use with a flushing fluid. The distal end face of the first bushing member is contoured to receive a mating proximal end face of the second bushing member or to also receive the abutting face of a packing ring or a lantern ring. The arrangement of the invention allows an operator to switch between the use of a mechanical seal or conventional packing without having to discard his primary seal cavity protector, as would be required in absence of the intention.
Patent CA-2355867-A1 (CA)
Inventor: PARSONS NATAN E
IPC: F04B43/08
Filed: 1999-12-23
Abstract: An automatic soap dispenser (10) includes a bellows-type collapsible container (18) of liquid soap. Constant-force springs (40 and 42) compress the container so as to expel the soap through a spout (16) when a valve-containing dispensing mechanism (20) permits it. When a sensor (14) detects an object such as a user's hand, a control circuit (56) operates the dispensing mechanism to permit soap flow through the spout for a predetermined time interval. Because of the constant-force springs, there is no need to use electric power to eject the liquid soap despite its typically high viscosity.
